Ore no Imouto ga Konna ni Kawaii Wake ga Nai, literally “My Little Sister Can’t Possibly Be This Cute,” is a Fall 2010 anime based on a light novel by the same name. Known as Oreimo for short, the series follows an “average” high schooler, Kyousuke, and his hardcore otaku of a younger sister, Kirino. Though only two episodes are out as of this writing, the show quickly explains the unwieldy title of the show by pointing out that “This Cute” basically means “like the loyal and affectionate little sister character you’d find in a moe anime or a visual novel.”
However, while the series emphasizes how Kirino is not “This Cute,” Kirino is shown to be so objectively good-looking that she works as a clothing model. Kyousuke expressing how he cannot see Kirino and her disrespectful, overachieving attitude as anything resembling adorability is akin to a man going into a crowd and loudly proclaiming his absolute hatred for chocolate. Even if he were telling the truth, an outburst like that would still make everyone think of chocolate.

The degree to which Kyousuke and the show itself remind the viewer that he is as far from a sister complex as possible reminds me of a certain situation in fanfiction, where an author notorious for creating Mary Sues, impossibly perfect characters often used as wish-fulfillment for the writer, tries to prove that they are capable of doing otherwise by creating extremely flawed characters. Ultimately though, these “Reverse Mary Sues” are just that: the tails to the Mary Sue’s heads, equally as “special” in terms of how much attention is given to them, even if it’s just about how imperfect they are.
Does that describe Kirino? Well, the easy assumption would be that Kirino exists on one side of the coin while the standard “moe little sister” resides on the other, but that wouldn’t be quite accurate. Kirino is not simply the opposite extreme, but more of a moe little sister character who also incorporates elements from the more established little sister archetype of smart-alec brat seen in American shows such as Boy Meets World and Full House and perhaps best exemplified in anime by Pop, the younger sister of the titular Ojamajo Doremi. Kirino, who nonchalantly disrespects her older brother, complains about a lack of privacy, and also expresses vocal disgust at the idea of a sibling romance, has those bratty qualities juxtaposed with the amount of time and effort the show devotes to putting Kirino’s cuteness on display.
By establishing Kirino as being not-cute-but-actually-really-cute, as well as giving her qualities closer to a more antagonistic and thus arguably more “realistic” younger sister, it begs the question of whether or not Oreimo is trying to diversify the concept of the moe “little sister” by incorporating those bratty elements, perhaps in response to any possible growing weariness with established and rigid moe tropes. In other words, could Oreimo be an attempt at reconfiguring moe from within, and if so, is that a sign of the times? Assuming these to be true, it would not be Kirino herself who equates to the Anti-Sue, but rather the genesis of Kirino as a new type of little sister bearing similarities to the initial motivation by which the Anti-Sue is formed, though handled with more skill and professionalism than your stereotypical fanfiction.
Further complicating the whole matter is the fact that Kirino herself is an otaku fanatically devoted to the “little sister” type who, instead of envisioning herself as the little sister yearning for the affections of her older brother, sees herself in the role of that fictional older brother. Moreover, Kirino is actually embarrassed about her hobby and is a closet otaku. When these aspects of Kirino are taken into account alongside Kyousuke and the degree to which he expresses his disinterest in little sisters both “real” and “fictional,” Kirino’s existence as an “attractive girl” actually takes priority over her existence as a “little sister” in certain respects. In particular, by making her the “otaku” and making Kyousuke the “normal one,” the (male) otaku watching may find themselves relating more closely to Kirino than her older brother, despite gender differences. That’s not to say that she is the viewer surrogate, of course, as Kirino is still very much designed to be the object of desire for the audience.

Essentially, Kirino’s charm starts to become that of a cute girl who is also someone’s younger sister, something is much more applicable to the real world than the typical visual novel archetype, seeing as how many females out there are younger sisters to someone. At the same time however, the trappings of Oreimo, namely the frequent and prominent use of the term “little sister,” also bring that fandom/fetish to the forefront of the viewer’s consciousness. Oreimo thus occupies a sort of contradictory space, where it appears to both reinforce and subvert little sister moe by being a variation on the established formula which also goes about reminding the viewer of that original formula. In doing so, the series then casts into question, perhaps unintentionally, the nature of the “little sister” character itself, as well as whether or not someone can enjoy a character who falls into a moe archetype without being specifically catered to by that archetype’s inherent qualities. Given such a contradiction, I have to wonder, is the overt “little sister” aspect of Oreimo a boon or a detriment? Or to put it another way, would Oreimo be better off if it weren’t about a little sister at all?
That all said, it’s only been two episodes. I’ll have to ask again at a later date.
